Any arguments to Tethereal after the command-line options are treated as
tokens in a filter expression (it behaves like tcpdump and snoop in that
regard). Therefore, it treated "/tmp/teste" as a filter expression, and
that's not a valid filter expression.
If you want to give Tethereal the name of a file to read, you have to do
it with the "-r" option:
tethereal -z io,phs -r /tmp/teste
